Technical Trivia Question - Mo or no Mo?
Last weekend, my 20 year old jar of wheel bearing grease rotted away (the package I mean). When I went to buy a replacement, I found that there were two types. The Ford type of grease has Molybdenum and the GM type does not. I know that I've been using the Mo formula for years on EVERYTHING that takes grease.
I looked in my various manuals and only found one refference that says to used Molybdenum based grease on the wheel bearings. Otherwise, nothing specific.
From this, several questions come to mind:
1) Does it matter one way or another? I can't imagine that lube shops have more than one can that they draw from.
2) What does the Molybdenum do? Enhance lubrication?
3) Is this question so trivial that it should go in "Off Topic?"
4) Any value in the synthetic grease? I'm a big fan of synthetic oils but am willing to admit that the difference may be fairly small. It is even smaller for grease?
Things to ponder on a Sunday morning.
it has a higher temp rating and doesn't dry up like standard grease. We use it in high voltage circuit breakers because the standard grease dries out and causes bad things to happen.
